PATENT HENRY KENNEY, OF NEW YORK, N. Y., ASSIGNOR TO HIMSELF AND ABRAHAM SLAIGHT, OF SAME PLACE.

MACHINE FOR BENDING IRON BARS.

SPECIFICATION forming part of Letters Patent No. 236,597, dated January 11, 1881.

Application filed May 1, 1880.

To all uihom tt may concern Be it known that I, HENRY KENNEY, of the city, county, and State of New York, have iiivented a new and useful Improvement in Ma- 5 chines for Bending Iron Bars, of which the following is a specification.

Figure 1 is a plan view of the improvement. Fig. 2 is a sectional side elevation taken through the line 00 a, Fig. 1. Fig. 3 is a sectional elevation taken through the line y y, Fig. 1.

The object of this invention is to furnish machines for bending iron bars for use in railroad work and other uses where angular braces or stays are required, and which shall be simple in construction, convenient in use, and powerful in operation.

The invention consists in constructing a machine for bending iron bars having a bedblock with inclined arms, a top block having inclined perforated and countersunk arms, the bolts and nuts, the spiral springs, and the pivoted cross-head having a lever, whereby the machine can be adjusted to bend differentsized bars, as will be hereinafter fully described.

Similar letters of reference indicate correspondin g parts.

A represents the bench or table to which the machine is secured.

B is the bed or base of the machine, which is secured to the bench A by bolts. The middle forward part of the base B is cut away to give space for the lever-handle to operate. Upon the end parts of the rear side of the bed B are formed two projecting arms, 0, the upper sides of which incline upward at an angle of forty-five degrees. The upper side of the middle part of the base B is made flat for the bar to rest upon while being bent.

Above the middle part of the base-block B is placed the top bar or block, D, the lower and forward sides of which are made fiat and meet each other at a right angle.

Upon the end parts of the rear side of the top block, D, are formed two projecting arms, E, which incline upward at an angle of fortyfive degrees, and have their lower sides made flat and smooth,t0 rest and slide upon the upper sides of the arms 0. The arms E are per (No model.)

forated longitudinally, to receive the rods or bolts F, which pass through and are attached at their lower ends to the bed-block B, and have hand-nuts G screwed upon their upper ends. The lower parts of the arms E are countersunk, to receive the spiral springs H, the lower ends of which rest upon seats formed to receive them upon the bed-block B. The spiral springs H are made sufficiently strong to raise the top block, D, when the nuts G are turned up.

I is a cross-head, upon the center of the outer side of which is formed a handle or lever, J. Upon the ends of the cross-head I are formed journals or pivots, which Work in bearings attached to the upper side of the end parts of the bed-block B. The inner side of the crosshead I is made flat and smooth, and is so arranged as to be level with the face of the bedblock B when the lever J is turned downinto a vertical position, and parallel with the forward side of the top block, D, when the lever J is raised into a horizontal position.

With this construction the top block, D, is adjusted to receive a thicker or thinner bar between it and the bed-block B, by turning the nuts Gr up or down, and the inclination of the arms 0 E will keep the forward side of the top block, D, always at the same distance from the inner side of the head-block I that its lower side is from the upper side of the bedblock B.

In using the machine, the lever J is turned down into a vertical position. The bar to be bent is inserted between the bed-block B and the block D.- The lever J is then raised into a horizontal position, which bends the bar at right angles, as shown in Fig. 3.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A machine for bending iron bars, constructed substantially as herein shown and described, consisting of the bed-block B, having inclined arms G, the top block, D, having inclined perforated and countersunk arms E, the bolts and nutsF G, and the pivoted crosshead I, having lever J, substantially as herein shown and described, whereby a bar of iron can be readily bent at an angle, as set forth.
